Might be worth talking to Guillaume and putting some informative text,
with a pointer, for the Wikitech newsletter.

Hi guys,
some time ago the '!' parser function was added in MediaWiki to 
replace the homonym template. However, the latter still exists on lots 
of WMF wikis.
I've come up with a rough tool 
<> to help 
identifying the wikis on which it's still on use and the ones on which 
it can be safely deleted. I've already made the server purge the link

only handle wikis you're familiar with ;-)
And don't forget to get the documentation page deleted too!
